As shown in FIGS.16-19, when the indicator 45 of the cap 40 is directed to or alignedwith the other indicium 17, such as 20 (lb), the shaft 50 is pivoted orrotated relative to the weight members 20-24 for an angle, and at thismoment, the uppermost pin 51 of the shaft 50 is offset from the opening31 of the uppermost weight member 20, but the other pins 51 of the shaft50 are aligned with the opening 32-35 of the other weight members 21-24for allowing only the uppermost weight member 20 to be attached to thereceptacle 10, and for preventing the other weight members 21-24 frombeing attached to the receptacle 10 (FIG. 19), and at this moment, thereceptacle 10 and the uppermost weight member 20 are weighed 20 lb.

Similarly, as shown in FIGS. 20-23, when the indicator 45 of the cap 40is directed to or aligned with the other indicium 17, such as 24 (lb),the shaft 50 is further pivoted or rotated relative to the weightmembers 20-24 for another angle, and at this moment, the upper two pins51 of the shaft 50 are offset from the openings 31, 32 of the upper twoweight members 20, 21, but the other pins 51 of the shaft 50 are alignedwith the opening 33-35 of the other weight members 22-24 for allowingonly the upper two weight members 20, 21 to be attached to thereceptacle 10, and for preventing the other weight members 22-24 frombeing attached to the receptacle 10 (FIG. 23), and at this moment, thereceptacle 10 and the upper two weight members 20, 21 are weighed 24 lb,for example. As shown in FIGS. 24-31, the cap 400 may include a socketopening 47 formed therein (FIGS. 24, 30-31) for receiving or engagingwith a spring biased projection or latch 48, and the actuating knob 600may include an engaging aperture or element 64 formed or providedtherein for selectively receiving or engaging with the spring biasedlatch 48 and for latching or locking the actuating knob 600 to thereceptacle 10 and the cap 400 selectively and for preventing theactuating knob 600 from being actuated or operated inadvertently by theuser.

Accordingly, the adjustable exercise device or kettlebell in accordancewith the present invention includes an improved compact structure forallowing the weight members to be easily and quickly and adjustablyattached to or disengaged from the weight carrier or handle and forallowing the adjustable kettlebell to be easily operated by the users.
